Ulix,
There was an unfortunate incident in 68 or so when just such an accident took
the life of an SCCA club racer. Rules were rewitten to require a nonresilient
head rest at certain dimensions from the drivers helmet etc. Understanding the
dynamics of these high force incidents is a must to ensure the protective
device does indeed not become the insrument of ones destruction. Certainly
there are advantages to be had from various protective systems but poorly
designed
devices will not give the maximum benefit.
Pay attention, and try to anticipate,
Cheers,
Ken
